BUCKLE.

Specification of Letters Patent.

Patented Mar. 1, .1910.

Application filed September 23, 1908. Serial No. 454,325.

To all whom it may concern:

Be it known that I, Aaron R. Conmourr, a citizen of the United States, residing at Alfred, in the county of York and b'tate of Maine, have invented certain new and useful Improvements in Buckles, of which the following is a specification.

This invention relates to buckles and refers especially to one which comprises a pivoted wedge lever.

The invention has for an object; the provision of a buckle which is of such construc tion that the greater the stress applied to the strap which is secured through the buckle the greater will be the proportionate resist:- ance of the buckle to release the strap.

The invention has for a further object a buckle of this description which is simple in construction, strong, durable and which can be economically nninutactured.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims with out departing from the spirit ot the invention.

In the drawings forming a portion 01 this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1. shows a side elevation of the buckle as secured to the opposite ends of a strap, Fig. 2. shows a view of the same with the buckle in an open position and one end of the strap released from the same, Fig. 3. is a top plan view ot the buckle in an open position.

Referring to the drawings, 10 designates a strap which is looped at one extremity to engage about one extremity 01'' a base 11 ot' a buckle which is centrally cut away and provided with a transverse bar 12 intermediately formed across its central portion. The base 11 is forked at one extremity in which is pivoted a lever 13 which comprises a metallie plate carrying at its free extremity two laterally and downwardly extending spring arms 14: which engage about the base 11 when the lever 13 is in a clamped position. The lever 18 is provided at its pivoted extremity with a cam 15 of semicircular tormation having the contacting surface thereof provided with a plurality of serrations for the purpose of frictionally engaging the opposite extremity of the strap or belt 10 which is passed through the belt 11.

lt will be noted that the forked portions oi the base upon which the lever 12-3 is supported are turned HpWtll'tlLY, to otl'set the pivot point of the lever from the plane o1 the adjacent inner portion of the base. It will also be noted that the end portion 01 the base at the extremity of which the strap .10 is secured, is also ott'set upwardly, whereby the lever 13 may be brought downwardly thereagainst; without interlerence by the portion 01 the strap disposed over the ba r 12, the arms 11 engaging resiliently over each side of the frame.

The method 01. using the belt is to insert the :tree extremity of the belt 10 upwardly through the forked extremity of the base 11 over the bar 12 and upon the loop-engaging end of the base 10. \Vhen the beltis in this position the lever 13 is forced downwardly im 'iinging the cam againstthat portion o1 the belt 10 which rests against the bar 12 and thereby prevents the belt 11) from slipping out of ei'igagcment with the base 11. For the purpose of holding the cam '15 securely in position the spring arms 1-1 are engaged over the opposite edges of the base 11 to clamp the lever 13 against the upper face of the free end of the belt 10. It is readily seen that with a buckle of this construction when .t'orce is exerted to withdraw the free end of the belt 1.0 from the base 11. the cam 15 is caused to wedge against the cross bar 12 and to force the serrated edge of the cam 15 against the face of the belt and so prevent the displacement; of the belt.

\Vhat is claimed is:-

1. A buckle cmnprising spaced side members, an integral strap-engaging portion connecting adjacent. ends of the side members, a cam revolubly mounted between the opposite ends of the side members, a cross bar spaced adjacent the cam, an operating lever carried by the cam, the space between the cam and the cross bar being adapted for the presentation of a strap therethrough to be clamped between the cross bar and the cam, the strap-engaging end of the device being oli'set to receive the lever thereagainst when in perative position and spring arms carried by the lever and adapted for resilient clamping engagement with opposite sides 01 the device to hold the lever in operative position.

2. A buckle comprising spaced side members, an integral strap-engaging portion connecting adjacent ends of the side members,

tit)

a cam revolubly mounted between the opposite ends of the side members, a cross bar spaced adjacent the cam, an operating lever carried by the cam, the space between the cam and the cross bar being adapted for the presentation of a strap therethrough to be clamped between the cross bar and the cam, the strap-engaging end of the device being offset to receive the lever thereagainst .0 when in operative position, and spring arms carried by the lever and adapted for resilient clamping engagement with opposite sides of the device to hold the lever in operative position.

In testimony whereof I aflix my signature, in the presence of two witnesses.
